Radiation Hardware

Radiation Hardware Quiz prep, practice quiz etc

The warming sleeve on the power injector is designed to keep contrast at a temperature of about: 37 degrees C
A patient's angulated x-ray view is 60 degree LAO, 30 degree cranial. In this view the image intensifier may touch the patient's Left shoulder
A contrast agent with an osmolarity of 300 milliosmoles would be considered: Iso-osmolar
A bulging or aneurysmal LV wall segment is termed: Dyskinetic
When you increase the X-ray tube filament temperature, you are increasing the: mA - you get more dots with more heat
T or F- X-rays can cause tissue damage because when they strike an atom of human tissue they may remove an orbital electron True
T or F? Internal mammary bypass grafts can be studied easily from the contralateral brachial approach False, should be ipsilateral/ same side for best view
When power injecting an LV gram which of the following would not be a setting that you could enter to direct the injection? Rate of rise or transition time; viscosity constant for contrast; pressure limit; duration of injection; vol. of injectate Viscosity constant for the contrast
What component of an X-ray system is positively charged? Rotating tungsten anode
The resolution in line pairs/mm of an imaging system describes all of the following EXCEPT: Image sharpness; Visibility of anatomical detail; Depth of penetration; Differentiation between closely spaced objects; Discrimination of small structures Depth of penetration
Characterstic radiation refers to x-rays generated by: dislodging a K-shell electron
Which of the following angiographic views would best display the aortic arch vessels? 45 LAO
In new x-ray systems, flat panel detectors are currently replacing the: cylindrical image intensifier
99% of the energy used by the x-ray generator exists in the form of: waste heat
Collimation of the x-ray beam involves filters made of: Lead
The rotating anode in the x-ray generator is made of : Tungsten
Chest leads made of carbon filament do not show up under fluoroscopy because they are: radiolucent
The most damaging radiation comes from the primary beam
One Sievert = 100 REM
100 RAD's = 1 Gray
in soft tissue 1 Gray approximately equals 1 Sievert (in soft tissue Grays and Sieverts are the same; 1:1)
Landauer reports indicate film badge exposure in Millirems
The reduction of electromagnetic energy as radiation passes trhought matter is called: Attenuation
The iodine in contrast is: Radio-opaque
Can x-rays be focused using electrostatic lenses? No, there is no charge in x-rays
Ionizing radiation damages tissue by: removing an orbital electron
mAs determines: the number of photons being produced
Coronary angio on a large pt in a steeply angulated view: the primary change made by the automatic cine exposure system to maintain adequate penetration is to increase: kV
Which of the following effects both the quality and quantity of the primary x-ray beam? kVp; mA; mAs; Exposure time; None of the above kVp because it also increases the mA
